Microform cleft lip or congenital healed cleft lip?

This paper presents the case of a patient with a visible scar indicating the occurrence of a cleft lip in the past. Anamnestic examination ruled out any facial surgery having been performed on the child and the parents confirmed the existence of the scar from birth. Intraoral examination revealed hypodontia of a lateral incisor on the side opposite the scar as well as hyperdontia of lateral incisors on the same side as the scar. This seems to confirm the existence of a cleft in the primary palate during gestation. A microform cleft primary palate is extremely rare and there are only isolated reports in the international literature relating to the spontaneous healing of such defects in utero.
